GHAFING-DISI-I LAMP.

Application filed February 25, 1911.

Specification of Letters Patent.

T 0 all whom it may concern:

Be it known that I, ALFRED H. S. SWAN, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Chafing- Dis"h Lamps; and I do hereby declarethefollowing to be a full and clear and exact description of the same,reference being had to the accompanying drawings, forming a part of thisspecification, and to the reference-numerals marked thereon.

The present invention relates to vapor lamps, such as are used withchafing dishes and cooking utensils of similar character, and has forits object to provide means for regulating the size of the flame openingin an etficient manner, whereby the volume of the flame may becontrolled.

To these and other ends the invention consists in certain improvementsand combinations of parts all as will be hereinafter more fullydescribed, the novel features being pointed out in the claims at the endof the specification.

In the drawings :Figure 1 is a vertical section of a lamp, embodying thepresent invention; Fig. 2 is a view in bottom elevation of the cover andflame regulating devices, showing the shutters closed; Fig. 3 is asimilar view showing the shutters open, and Fig. 4 is a similar viewwith the shutters closed, the shutter controlling plate being. removed.

Similar reference numerals throughout the several figures indicatesimilar parts.

In the present embodiment, the invention type generally, used withchafing dishes, and in this instance comprising a lamp body 1 and font 2adapted to contain asbestos or other suitable material for holding thealcohol, or similar vaporizing fluid, the asbestos being retained withinthe font in'the usual manner.

The lamp body 1 is provided with a suitable cover 3 which may be securedin any desirable manner, and has an opening 4 centrally thereof. Asupporting plate 5 is fixedly mounted on the cover, and has securedthereto the friction rollers 6, for a purpose which will be presentlydescribed.

Arranged between the top of the cover and the supporting plate 5 are theshutters 7 which are held in pivotal engagement with the cover in anyconvenient manner as by means of rivets 8. The shutters 7 have ears 9extending rearwardly from their pivotal points and provided with slots10. The difficulty has been, in devices of this character, to provideefficient means for properly controlling the movement of the shutters,and to this end, in the embodiment of the invention herein disclosed, Iemploy an annular trolling plate accommodate the rollers 6 of thesupporting plate, the rollers engaging the edge of the plate within thecut-away portion and permitting a free, easy movement of the parts.

The controlling plate 11 carries pins or lugs 14 which project throughopenings 15 arranged circumferentially in the supporting plate 5, andengage the slots 10 in the shutters, so that as the controlling plate isrotated, the shutters will be moved'on their pivots correspondinglytoward open or closed positions, according to the direction of movementof the controlling plate.

The controlling plate is provided with downwardly extending fingers 16with which the means employed for operating the plate cooperates, saidmeans comprising a crank 17 carried by a rod 18 which has at its outerend an operating handle 19, the rod 18 being supported in any suitablemanner as by a bracket 20 mounted on the lamp body. The cover 3 iscut-away, as designated at 21, providing a recess receiving bracket 20.l

' To regulate the size of the flame, the handle 19 is turned, causingthe controlling plate to be rotated within the cover, and

the shutters to be opened or closed by their connection with thecontrolling plate. By this means it is possible to obtain a quick actionof the shutters and a correspondingly quick control of the flame, by asimple action of the parts, which are few in number and may be readilyassembled in the manufacture of thelamp.

I claim as my invention.

In a vapor lamp, the combination with a lamp body and a cover havingan opening therein, of a pair of shutters pivoted to the cover andcooperating to close the opening, a controlling means operativelyconnected to the shutters for opening and closing the same, theconnecting points of the controlling means with the shutters beingadjacent to the pivotal points of the shutters, the

controlling means being slidably mounted in the cover and movable in anannular path to actuate the shutters. 2. In a vapor lamp, thecombination with a lamp body and a cover having an opening therein, of apair of shutters pivoted to the cover and cooperating to close theopening, controlling means operatively connected to the shutters foropening and closing the same, the connecting points of the controllingmeans with the shutters being adjacent to the pivotal points of theshutters, the controlling means being slidably mounted in the cover andmovable in an annular path to actuate the shutters, and -a rotatableoperating handle adapted to effect movement of the controlling means.

3. In a vapor lamp, the combination with a-lamp body and a cover havingan opening therein, of a pair of fiat shutters pivoted to the cover andcooperating to close the opening, controlling means comprising a plateoperatively connected to the shutters for opening and closing the same,the connecting points of the controlling means with the shutters beingadjacent to the pivotal points of the shutters, and a rotatableoperating handle having connection with the controlling means.

4:. In .a vapor lamp, the combination with a lamp body and a coverhaving an opening therein, of a pair of shutters pivoted to the coverand cooperating to close the opening, said shutters being provided withslots, controlling means comprising a plate slidably mounted in thecover and movable in an annular path, pins carried by the plate andengaging the slots in the shutters atpoints adjacent to the pivotalpoints of the shutters, and an operating handle adapted to' actuate thecontrolling means.

5. In a vapor lamp, the combination with a lamp body and a cover havingan opening therein, of a pair of shutters pivoted to the cover andcooperating to close the opening, said shutters being provided withslots, controlling means for the shutters comprising a plate slidablymounted in the cover and movable in an annular path, pins carried by theplate and engaging the slots in the shutters at points adjacent to thepivotal points of the shutters, a fork carried by the plate, anoperating handle, and means movable with the handle and cooperating withthe fork to actuate the controlling means.

6. In a vapor lamp, the combination with a lamp body and a cover havingan opening therein, of a pair of shutters pivoted 'to thecover-andcooperating to close the opening, the shutters being providedwith slots, con

trolling means comprising a plate slidably movable in a circular path, asupporting plate attached to the cover and positioned between theshutters and the controlling plate, the supporting plate being providedwith openings, guides mounted on the supporting plate, and thecontrolling plate having cut-away portions cooperating with the guideson the supporting plate, pins carried by the controlling plate extendingthrough the openings in the supporting plate and engaging the slots inthe shutters, and an operating handle adapted to actuate the controllingmeans.

8. In a vapor lamp, the combination with a lamp body and a cover havingan opening therein, of a pair of shutters pivoted to the cover andcooperating to close the opening, the shutters being provided withslots, controlling means comprising a plate slidably mounted in thecover and movable in a circular path, a supporting plate attached to thecover and positioned between the shutters and the controlling plate, thesupporting plate being provided with openings, guides mounted on thesupporting plate, and the controlling plate having cut-away portionscooperating with the guides on the supporting plate, pins carried by thecontrolling plate extending through the openings in the supporting plateand engaging the slots in the shutters, a fork carried by thecontrolling plate, an operating handle, and means movable with thehandle and cooperating with the fork to actuate the controlling means.
